Fill a large pot with water and bring to a boil over high heat. Add a small handful of salt and the bucatini to the boiling water.
Cook the pasta, stirring occasionally, until al dente, about 6 to 8 minutes. Drain the pasta, reserving 2/3 cup of the pasta water.
Pour the pasta back into the pot or into a large skillet and place over low heat. Add the reserved pasta water and butter, tossing together until the butter just melts.
Add the grated Pecorino Romano and black pepper, and continue to toss together until the cheese melts and a creamy sauce forms.
Top with more grated Pecorino Romano and serve immediately.
